Nice HD for almost 12 months


Need to contact Plextor Monday

Good read write and nice clone software

Laptop is getting laggy these last 4-6 weeks with regens, read and writes, while using AutoCAD and Revit. Presumed it was the may be the video card or perhaps HD ; Had time to spend troubleshooting. Its the HD failing ; Did a SMART check and received...

The first one failed, but NewEgg made it right!


In the future, I will likely choose a faster shipping method, unless I truly do not care when the order arrives. I do not understand why the cheaper shipping arrangement involves two carriers, and is not handled by a single carrier. That would seem to...

I ordered a Plextor PX-256M5Pro SSD, and when it arrived, it worked for a few hours, then failed to be recognized on my computer. A call to the Plextor tech site, proved the SSD was faulty. I then called the NewEgg site, and explained the problem....

No one likes an item to fail, but products (like people) are not perfect. The only disappointment regarding the failure episode was MY choice of shipping options. I had selected the no-cost EggSaver option on the original order, and the replacement was...

SSD is boss


If you aren't sure how to install SSD's, how to add storage drives, and how to move your files, then check out YouTube and look up NewEgg and there you'll find lots, I mean lots of great 'How-To' videos for how to do it right. I've been building...

Works exactly as it should. This was my first venture into SSD's and I couldn't be happier. Just remember to only use SSD as your bootdrive. Get a large (1TB or higher) HDD for your storage drive. Move all your heavy files such as music, photo's,...

Not compatible with Alienware m11x


Plextor wanted me to pay to return the drive for the RMA.

Fast, like most SSDs

Not compatible with my Alienware m11x which was the intended recipient of this drive ; The drive was not visible in the bios at all ; I ended up installing it in my XPS15 and worked fine there

Plextor M5Pro


Reliable so far. I replaced an OCZ Agility 3 that was a disaster turning off the computer 2-3 times a day with this one that perform a lot better. Nothing spectacular but it does the job

Getting Sequential Read of 380 MB/s and Sequential Write of 215 MB/s on SATA III 6Gbps. NOT even close to what manufacture claims. Those readings were on an ASUS Extreme IV MOBO with 32MB RAM and an Intel i7 3930K

READ this: Packing Info


Install and use the drive ASAP so you don't let the warranty expire and then discover problems! Plextor gave me very good support when I called 5 minutes after receiving the shipment from NewEgg Tuesday 1PM after ordering last Sunday. Great! WOW. I...

Pay attention to the packaging. The box contains a flip-cover box with all the necessary contents. The bracket is ingeniously packed with the sides poked through slots in the bottom of the flip-box, around the SSD. A flap inside the flip-cover contains...

No big deal, but Plextor should reprint their Quick Install Guide so it does not mention the cloning software on CD "provided", and directs the customer to download the software from the URL with the provided Keys on the Flip-box top
